Chicago Exchange to Extend
Its Hours After SEC Ruling

The Chicago Stock Exchange is to extend its close to 6:30 p.m. Eastern time on Oct. 29, following approval of the plan by the U.S. Securities and Exchange Commission.

Because of the approval, announced Thursday, the consolidated "tape" of prices and quotes in New York Stock Exchange-listed stocks will also stay open until 6:35 p.m., effective Oct. 29, an NYSE spokesman said. The Big Board itself will close at 4 p.m. as usual.
